` In the accompanying drawing- Figure 1 represents a verticallongitudinal section of the machine, taken on theline x a: of iig. 2. vFigure 2 is a vertical cross-section, taken on. the

.line yy of fig. 1.

Si nilar letters ofreference indicate corresponding parts.

A and B are head-blocks, which support the cylinvder'and concave ofthemachine.

j Gis the cylinder, which may be lnted or serrated, or covered withtinted or serrated sheetmetal, as may be found most advisable. l v D isa bedpiece, which .connects the two heads A and B together. y l kE is-tne concave, which is composed of rollersA 11,

(more or less in number.)

lhese rollers lhave journals or pivots at their ends,

`and revolve by the actionV of the-cylinder over the j lothes. Theclothes to be washed are 'placed between t le cylinder and the concave,the former being-revolved back and forth by means of the crank G.

- H is a gear-wheel on the end ot' the cylinder-shaft.

. is placed for washing.

I is ashaft which extends across the machine above the cylinder, uponwhich there is a pinion-wheel J,

which enga-ges with the wheel H. The crank Gr is on the end ot' thisshaft.

'lhe journal of the cylinder and of thc shaft Ivrevvolve iu boxes, whichare confined in vertical slots in the heads so that theypmaybarca-vertical motion.

- K isa spring', which extends across theI machine above the' shalt G,the ends of wlich bear upon the journal-boxes.

This arrangement is seen in fig. 1, where L L represent the boxes.

M is an adjusting-screw, which; works through the cap-piece N, by meansof which more or less pressure may be brought to bear upon the' cylinderand ou the 4 clothes beneath it.

0 is the tub in which the above-described machine 'lhe machine 'isfastened in the tub by meansof spurs in one of the heads and al'buttonou the other, or in any other suitablelmalmer. j
